What is MAC Address Generator Online?

A MAC (Media Access Control) address is a 48-bit hardware identifier for network interfaces, expressed as 6 colon-separated hex octets (e.g. 00:1A:2B:3C:4D:5E). Virtual machines require MAC addresses for network configuration. The first 3 octets identify the manufacturer (OUI); the last 3 are device-specific.

Frequently Asked Questions

Locally vs globally administered MAC?

Globally administered MACs are assigned by the manufacturer. Locally administered (bit 1 of byte 1 = 1) are custom-assigned — safe for VMs and test environments.
